1. A liquid crystal display device having dynamically switching driving modes, comprising:

  • a liquid crystal panel comprising a plurality of liquid crystal capacitors for displaying an image;

    an input interface for generating a scan control signal;

    an oscillator for generating a predetermined frequency;

    a control unit, electrically coupled to the oscillator, for outputting a first current control signal when a frequency of the scan control signal is lower than the predetermined frequency; and

    a driving circuit, electrically coupled to the controller, for generating a first bias current to charge the plurality of liquid crystal capacitors based on the first current control signal.
